Hi Guys, Looking for some support on a new build I've put together that I'm unable to get to post.. Where I Am Now : System connected up to PSU and connected to monitor with DVI output via GPU. (Monitor set to DVI primary) Powering on PSU lights up Motherboard as expected. Triggering on button - Mobo / CPU fans are audible. Triggering on button - All 8 x Dimm slots & GPU light up as expected. Motherboard LCD output runs through a few codes then posts "Memory Code AD - Detect Memory" and there is nothing posted to display. Troubleshooting Up to now : Rebooting several times (the hope and pray method us lesser folk default to the first few times). After failed start up, turned off machine, disconnected all cables from Motherboard, waited 30 minutes, held restart CMOS for 5 seconds. Re-plugged cables into Motherboard / components and powered on. Wrote this topic on this forum. System Specifications : Asus Zenith Extreme X399 (2018 model) AMD Threadripper 2950X 128GB (8x16GB) Corsair Vengeance RGB Pro 3466Mhz 1 x 1TB Samsung 970 Pro M.2 1 x 4TB Samsung 860 Pro 2 x EVGA 1080TI FTW3 1 x EVGA T2 1600W PSU Appreciate any support or advice rendered! Thanks - TGM.
